To all 'whom t may concern.'

Be it known that we, ERIK TIMANDER and GsrA TIMANDER, subjects of the King of Sweden, residing at Ursa, Sweden, have invented new and useful Improvements in Lifting Apparatus for vRailway Tracks, of which the following isa specification.

This invention relatesto an apparatus for lifting of railway tracks or the like. The apparatus is of the type in whicha stopping member is automatically pushed in under the track, when the latter is liftedy by means ofva double armed lever, and the object of the invention is the construction of an4 easi- .ly vmanaged/and effective lifting apparatus, `in which the forward pushing of the stopping member may be easilyl effected, independently ,oft-he constructionof the apparatus as a Vwhole `and of the load on the lever, while at the. same time the apparatus is balanced as completely as possible. for

"preventing any oblique position of the stopping member or even any tendency of `taking up such a position.

A vconstructional form of the invention is illustrated in the accompanying drawing. Fig. lis a longitudinal section'on the line I-I 0f Fig. 2, Fig. 2 a plan'view and Fig. l3 a cross l sectionA on the `line III-III of Fig. 1; Fig. 4 is a detail View.

The lever 1 which preferablyv is made from steel andof a redt-angular cross section and its lower'end is shaped as a hook 2 with horizontal -studs 4. The bearing or lifting member for-.the said lever consists Vof two plates 5 suitably of a triangularshape and connected 'bystays, a fore'l and a back stay, Gand-7, which may be in one piece. Theupward turned, sloping edges of `these plates are provided with notches 8,A in which the; studs 4 maybe pivoted. The distance between the two plates 5 is such, that the lever 1 can be moved freely between them.V Outside each of these plates 5 another plate 9 of the same shape is situated, .the sloping upperV edge of which has the same inclination to the base edge as the corresponding edges rof the plates 5.

` vThe edges of the plates-9 are provided with teeth 10 `and the two plates V9 by vmeans 'ofj-a Across piece 1l are united to a lift- 'ingk member. vThe cross piece 11 runs `through the elongated slots 13 inthe plates 5 which slots open in the ledge of ea'ch'plate y5 vat :12. The two pairs lof plates 5 and 9 thus are connected in such amanner. that they can be disengaged from one another` and at the ksaine time they are movable hori- Zontally in relation to one another, which movement, however, is limited by means of the slots 13, so that itbecomes a little larger than the horizontal distance between two adjacent notches 8 in the plates 5.

The lifting member 5 as well as the stopping member 9, 11 are movable upon a base plate 20, provided with a longitudinal groove 14y in which the stays 6 and 7 of the lifting member 5 project. The ystopping member 9, 1l is provided with angular flangesy l5 forming guides for oth-er flanges 16 on the ybase pla-te 20. AThe backward movement of the lifting member 5 is limited by a' stud 17 which is vertically adjustable `in the base plate and locked in stopping po- `29 are arranged, which determine the position of the plate in relation to the rail, when v4the baseplate isbrought under the latter. .In vthe middle of the base plate there is'y further lan opening 30 forv the hook n kshaped part 2 of the lever 1.v

-The teeth 10 are arranged upon special lists 3,5, which on the underside are provided .with studs 36, corresponding to borings inthe plates 9, in which boringsy they after insertion may be locked by means of screws 3.7 inserted fromv the side of the plates. `The lists thus are exchangeable.

In using the apparatus the two members 5 and 9, 11 must be drawn backward on the base platev 20 so far as possible, whereupon the said plate 20 is pushed under the rail 40 until the projections 29 bear against the foot of thev rail.'v Thestuds 4 of the lever 1 Inow are placed in the l undermost notches 8` and theV vliftingv member 5 is pushed forward, so that the hook 4shaped end of the lever- 1 grasps under the foot lof the rail. n lifted bythe levervthe stopping jmember on account of the springs 2l is brought forward under the foot of the rail and supports it, if the lifting operation is interrupted.

Having now particularly described the nature of our invention and the manner of its operation, what we claim ist l. A lifting apparatus for railway tracks, comprising a base plate, a lifting member movable thereon and consisting of two firmly united plates situated at a distance from one another and provided with a series of notches, a movable stopping member, consisting of two united plates one on cach side of the lifting member and each provided with teeth the said two members being connected by springs which are stretched at a forward motion of the lifting member and thereby tend also to move the stopping member forward, and a detachable lifting lever between the two plates of the lifting member, the said lever being provided with studs to be placed in the notches of the lifting member.
